Cumulative Frequency Polygon
In statistics, the cumulative frequencies of a dataset are shown graphically using cumulative frequency polygons. The dots at the upper-class borders are plotted against the corresponding cumulative frequencies to create the graph. The graph illustrates the visual accumulation of data across time or intervals. The polygon created by the line connecting the points aids in the visualization of the data’s trends and patterns.
It helps analysts grasp the structure and central tendency of cumulative frequency distributions by clearly showing them. Researchers and analysts may get important insights into the distribution of the data and make wise judgments based on the trends seen by employing cumulative frequency polygons.
Frequency Polygons in Statistics
Frequency Polygons in Statistics: A frequency polygon is a type of line graph where the frequencies of classes are plotted against their midpoints. This graphical representation closely resembles a histogram and is typically used for comparing data sets or showing cumulative frequency distributions. It uses a line graph to represent quantitative data.
Frequency polygons are one of the great methods to represent statistical data so that it can be read easily. In statistics, we deal with lots of data, and reading it quickly is necessary for solving statistical problems effectively.
Frequency polygons help us to achieve the same result. In this article, we will learn about frequency polygons, their formula, examples, and others in detail.
